Publication number: 20040164293Abstract: The present invention involves a low-temperature, photoresist-free method of fabricating a barrier layer on a flexible substrate. An embodiment involves the conversion of a precursor into a top-surface imaging layer during a direct patterning step. Preferred precursors are formed from a metal complex comprising at least one ligand selected from the group consisting of acac, carboxylato, alkoxy, azide, carbonyl, nitrato, amine, halide, nitro, and mixtures thereof and at least one metal selected from the group consisting of Li, Al, Si, Ti, V, Cr, Mn, Fe, Ni, Co, Cu, Zn, Sr, Y, Zr, Nb, Mo, Ru, Rh, Pd, Ag, In, Sn, Ba, La, Pr, Sm, Eu, Hf, Ta, W, Re, Os, Ir, Pt, Au, Pb, Th, U, Sb, As, Ce, Mg, and mixtures thereof.Type: ApplicationFiled: May 20, 2003Publication date: August 26, 2004Inventors: David J. Maloney, Wai M. Lee, Paul J. Roman, Michael A. Fury

Publication number: 20040072439Abstract: A composition for chemical mechanical polishing includes a slurry. A sufficient amount of a selectively oxidizing and reducing compound is provided in the composition to produce a differential removal of a metal and a dielectric material. A pH adjusting compound adjusts the pH of the composition to provide a pH that makes the selectively oxidizing and reducing compound provide the differential removal of the metal and the dielectric material. A composition for chemical mechanical polishing is improved by including an effective amount for chemical mechanical polishing of a hydroxylamine compound, ammonium persulfate, a compound which is an indirect source of hydrogen peroxide, a peracetic acid or periodic acid. A method for chemical mechanical polishing comprises applying a slurry to a metal and dielectric material surface to produce mechanical removal of the metal and the dielectric material.Type: ApplicationFiled: October 10, 2003Publication date: April 15, 2004Applicant: EKC Technology, Inc.Inventors: Robert J, Small, Laurence McGhee, David J. Maloney, Maria L. Peterson

Patent number: 6696363Abstract: The present invention relates generally to a method and apparatus for converting a precursor material, preferably organometallic, to a film, preferably metal-containing, that is adherent to at least a portion of a substrate. Both method and apparatus include a pre-conversion step or section, and a step or section for substantial conversion of a portion of material from the pre-conversion step or section into the form of a predetermined pattern, wherein this substantial conversion results in a metal-containing patterned layer on the substrate.Type: GrantFiled: June 6, 2001Date of Patent: February 24, 2004Assignee: EKC Technology, Inc.Inventors: Wai M. Lee, David J. Maloney, Paul J. Roman, Michael A. Fury, Ross H. Hill, Clifford Henderson, Sean Barstow
